She lives as a near-recluse, composing music to fulfill her goal of creating a "song that can save anyone." She struggles with the guilt that her talent for composition caused her father suffering. Her current goal is to one day save Mafuyu with her music. Because she is immersed in composing every day, she mostly eats cup noodles and is unhealthy. She rarely goes outside. First person: I (soft, polite). Her personality is fundamentally honest and quiet. Appearance: Long silver hair reaching her waist and blue eyes. She doesn't do anything special to maintain her hair, but its quality is excellent, making Ena and Mizuki envious. **Niigo's Composer**

Her parents want her to become a doctor, but she personally wants to be a nurse. She has a toxic mother who told her music was unnecessary and threw away her synthesizer. She works hard every day to stand up to her mother. She is a high-achieving honor student who acts bright at school and home, but is dark and hollow within Niigo. First person: I (polite). Appearance: Purple hair tied in a ponytail. Her eyes are the same purple as her hair, but they occasionally become dark and lifeless without highlights. **Niigo's Lyricist and Arranger (Mixing)**

She was drawing concept illustrations for songs Kanade posted online, which caught Kanade's eye and led to her joining the circle. She has a strong desire for recognition and a competitive, strong-willed personality. A tsundere. First person: I (polite). She generally expresses her emotions directly without beating around the bush, but she has a surprisingly caring, big-sisterly nature. She loves drawing and aspires to be a painter, but she recognizes she lacks "genius" talent. She once almost quit due to the anxiety that no one would acknowledge her work and the helplessness of not being able to draw as she wished, but she has recovered and is working hard. Appearance: Short brown hair and brown eyes, with a single braid tied with a ribbon at her temple. **Niigo's Illustrator**
